A seating indicator for loadbreak connectors and deadbreak connectors that includes a substantially round, elastic O-ring having a body and an opening, wherein the O-ring is installed on the transition shoulder portion of a loadbreak bushing insert, and wherein the O-ring extends radially and outwardly from the bushing insert when an elbow connector is properly installed thereon. The O-ring can be hollow so that it will more easily deform and can be made from an elastomeric material in easily viewable colors.

Triglyceride and other polyol ester PVC plasticizers can be produced by recovery of branched C6 to C9 aldehydes from a hydroformylation product, optional hydrogenation to the alcohol, oxidation to the acid with oxygen and / or air, recovery of the resulting acid, and esterification with glycerol, ethylene glycol, propylene glycol or mixtures thereof. The branched alkyl chains comprise at least 10% methyl branching. Special triglycerides are derived from branched aliphatic acids having alkyl chains with average carbon numbers from 6 to 9 and at least 10% methyl branching. These triglycerides are fast fusing plasticisers if before esterification with glycerol, an aryl acid is introduced together with the aliphatic acids.

The present invention relates to a polymeric composition which has an excellent combination of properties for use in making seals and gaskets for utilization in appliances, automotive applications, and building applications, such as window glazing gaskets. These polymeric compositions offer excellent dimensional stability, low compression set, outstanding sealing characteristics, low temperature flexibility, heat resistance and ultra-violet light resistance. The present invention more specifically discloses a polymeric composition having excellent characteristics for utilization in manufacturing seals and gaskets including dimensional stability, low compression set and outstanding sealing characteristics, said polymeric composition being comprised of a blend of (A) a thermoplastic resin selected from the group consisting of polypropylene, polyethylene, poly phenylene ether, polystyrene, and styrene containing copolymer resins, (B) an elastomeric polymer selected from the group consisting of block copolymer comprising a first polymeric block that is comprised of repeat units that are derived from a vinyl aromatic monomer and a second block that is comprised of repeat units that are derived from a conjugated diolefin monomer, wherein the repeat units in the second block are hydrogenated, and wherein the repeat units in the second block are elastomeric in nature, and a crosslinked olefinic elastomer, (C) a high molecular weight crosslinked diene elastomer comprised of repeat units that are derived from conjugated diene monomer selected from the group consisting of 1,3-butadiene and isoprene, wherein the high molecular weight diene elastomer has a weight average molecular weight of at least about 200,000, and (D) an oil.

Amorphous poly-alpha-olefins (APAOs) such as propylene-co-hexene-1-co-butene-1 and propylene-hexene-1 are used as tackifiers in hot melt adhesive formulations.

A method for waterproofing a substrate, the method including adhering an adhesive member obtained by using an active hydrogen-containing synthetic resin, to a urethane-based waterproof layer to laminate a pavement adhesive layer; applying or spraying an isocyanate group-containing compound onto the pavement adhesive layer; and paving an asphalt mixture on the surface of the pavement adhesive layer.
